Perioperative myocardial injury in patients undergoing non-cardiac surgery is a major challenge in the vascular surgical practice. It can be missed if we don’t look for it, but it was found to be associated with early (30-day) and late (1 yr) morbidity and mortality. Puelacher C et al defined Perioperative Myocardial Infarction (PMI) as an absolute high-sensitivity cardiac troponin T increase of ≥14 ng/L from preoperative to postoperative measurements. In their large study (2546 surgeries) PMI occurred in 16%, but it was accompanied by chest pain only in 6%, any type of ischemic symptoms in 18%. Crude 30-day mortality was 8.9% in patients with PMI versus 1.5% in patients without PMI. There is a potential to help many of the 8 million adults globally who have PMI(MINS) to reduce their risk of a major vascular complication. If only we can identify these patients and apply appropriate medications, we can prevent this mortality and morbidity.
